Abstract
The invention relates to a manufacturing method for a cable core wire insulating layer. The prepared cable core wire insulating layer comprises a calcium carbonate-glue mixing layer, a glue layer and a calcium carbonate layer. A cable core wire is wrapped by the calcium carbonate-glue mixing layer which is wrapped by the glue layer. The glue layer is wrapped by the calcium carbonate layer. The calcium carbonate-glue mixing layer is formed by using the cable core wire through the glue layer first and then through a fluidized bed and an extrusion device. A glue pool is full of glue. The fluidized bed is filled with calcium carbonate powders which are fluidized. Then the whole system is through a heat-curing device in which temperature is controlled between 100 and 120 DEG C, glue is cured and the whole process is completed after cooling. The cable core wire insulating layer is internally provided with a large amount of calcium carbonate materials so that use amount of high-molecular materials is effectively reduced, and thus production cost of cables is reduced.

In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of manufacture method of cable core insulating barrier, the manufacture craft that comprises core apparatus and the cable core insulating barrier of preparing cable core insulating barrier, the core apparatus of preparing cable core insulating barrier comprises glue pond, fluid bed, pressurizing unit and the device that is heating and curing, glue is full of glue in pond, the calcium carbonate powder being fluidized is placed in fluid bed, pressurizing unit is with the wheel of a depression, wheel clamping cable core by depression also applies the effect of power simultaneously, cable core material outer layer structure is fully pushed, the temperature of device of being heating and curing is controlled between 100 to 120 degrees Celsius, can play solidification to material.
A manufacture craft for cable core insulating barrier, comprises the following steps,
Step 1, cable core, by the first glue pond, form glue layer outward at cable core;
Step 2, by step 1 with the cable core of glue layer by the first fluidized bed, at glue layer, form calcium carbonate layer outward;
Step 3, will in step 2, with the cable core of glue layer and calcium carbonate layer, send into pressurizing unit, by the effect of pressure in pressurizing unit, glue layer and calcium carbonate layer are fully pushed, form the mixed layer of calcium carbonate-glue;
Step 4, by the cable core with calcium carbonate-glue mixed layer forming in step 3 by the second glue pond, at calcium carbonate-glue mixed layer, form glue layer outward;
Step 5, by the cable core with calcium carbonate-glue mixed layer and glue layer forming in step 4 by the second fluid bed, at glue layer, form calcium carbonate layer outward;
Step 6, the cable core with three layers of outside embracing layer of making in step 5 is sent into the device that is heating and curing, control temperature between 100 to 120 degrees Celsius, glue is cured.
Beneficial effect of the present invention is: the manufacture craft that the invention provides a kind of cable core insulating barrier, the cable core insulating barrier of making comprises calcium carbonate-glue mixed layer, three layers of glue layer and calcium carbonate layer, in cable core insulating barrier, contain a large amount of calcium carbonate materials, this will effectively reduce the use amount of macromolecular material, and then the production cost of reduction cable, in addition, calcium carbonate material character when breaking out of fire can not change and can not burnt by big fire, like this, when breaking out of fire, calcium carbonate layer can effectively completely cut off adjacent cable core to come, avoid the generation of short circuit accident.
